Welcome to healthcare Magic forum..
I am sorry to hear about your baby..
VSD is congenital heart disease
where in you find a hole in your baby's heart!!
In 25% cases the defect closes by itself..VSD is closed by a surgical procedure where in your baby's chest and heart is opened and defect is closed using a patch. But if the size is small a VSD device closure can also be done, where closure is done through a vessel in the leg..Since your baby is experiencing symptoms, I would suggest you to consult a cardiologist
and CTV surgeon who could further decide upon the further management of your baby..
Hope this helps!!
